Using the information presented in the following table, identify the processing sequence that would result

using priority rules $(1)$ MST$,(2)$ SPT$,(3)$ EDD, and $(4)$ CR$.$ For each priority rule, determine $(1)$ average flow

time, $(2)$ average hours late, and $(3)$ average WIP. Is one priority rule superior to the others?

Explain. $($Hint: First determine the total job time for each job by calculating the total processing time for the

job and then adding in the setup time. All times are in hours.$)$
